Audi ConceptAuto enthusiasts beware: you may have to pick your jaw up off the floor after reading this article: Audi released a concept RS TDI that packs an unbelievable punch and I want one now. Not tomorrow, not after breakfast- *now*.

The concept car is powered by an insane 3.0-liter biturbo boosted by an electrically driven turbocharger. Remember those days when people would laugh when someone bought an "electric supercharger" off eBay? Well electric turbos are here, and they're propelling this concept to 100km/h (62.1mph) in just four seconds with its 385hp and tire scorching 553lb-ft of torque....

So you can go from 0 to 60 in four seconds. Where can you actually do that legally in this country?

Greatest line I ever heard (this moments after thanking a guy I was visiting in Denmark for taking my for a ride on the Autobahn in his Porsche 911): "Why do you Americans buy sports cars when you cannot use them properly?"
